1 tnHeb “like light of brightness.” This construction is an attributive genitive: “bright light.” The word “light” (אוֹר, ’or) refers to the early morning light or the dawn (BDB 21 s.v.). The point of the simile is that the course of life that the righteous follow is like the clear, bright morning light. It is illumined, clear, easy to follow, and healthy and safe – the opposite of what darkness represents.

2 tn The construction uses the Qal active participle of הָלַךְ (halakh) in a metaphorical sense to add the idea of continuance or continually to the participle הוֹלֵךְ (holekh). Here the path was growing light, but the added participle signifies continually.

3 tnHeb “until the day is established.” This expression refers to the coming of the full day or the time of high noon.
